Outcomes
The severity of a traumatic brain injury (TBI) may range from “mild,” i.e., a brief change in mental status or consciousness, to “severe,” i.e., an extended period of unconsciousness or amnesia after the injury.
CDC estimates that at least 5.3 million Americans currently have long-term or lifelong need for help to perform activities of daily living as a result of a TBI.1
TBI can cause a wide range of functional changes affecting thinking, sensation, language, or emotions.
-
Thinking (i.e., memory and reasoning);
-
Sensation (i.e., touch, taste, and smell);
-
Language (i.e., communication, expression, and understanding); and
-
Emotion (i.e., depression, anxiety, personality changes, aggression, acting out, and social inappropriateness).2
TBI can also cause epilepsy and increase the risk for conditions such as Alzheimer’s disease, Parkinson’s disease, and other brain disorders that become more prevalent with age.2 |

About 75% of TBIs that occur each year are concussions or other forms of mild TBI.3 Repeated mild TBIs occurring over an extended period of time (i.e., months, years) can result in cumulative neurological and cognitive deficits. Repeated mild TBIs occurring within a short period of time (i.e., hours, days, or weeks) can be catastrophic or fatal.4
